The nDVR 540 is a digital video recorder (DVR) surveillance system designed for use 
with existing CCTV cameras, which the company says eliminates the need for re-cabling, cable splicing, or camera recalibration. The DVR supports 4-channel CCTV cameras and offers real-time recording and display via H.264 compression. In addition, the product can be managed by multiple users from remote online locations and from most mobile devices, including the Android, iPhone, and iPad. A 10-sec pre-alarm buffer on event recording prevents the loss of important video, and an email notification option notifies security personnel of the alarm.
